Almost Ideal Contrast Visual Cryptography with Reversing
Duong Quang Viet and Kaoru Kurosawa
Abstract
A drawback of visual cryptography schemes (VCS) is much loss of contrast in the reconstructed image. This paper shows a new paradigm of VCS in which the original image is almost perfectly reconstructed. A very simple non-cryptographic operation is assumed, reversing black and white, which many copy machines have these days. We first show a
